Today I had to mount a NFS linux machine (e.g. 192.168.33.33) from an AIX client.
So I noticed the “normal” mount command may not work:

# mount 192.168.33.33:/opt/something /home/guest/tmp
mount: 1831-008 giving up on:
192.168.33.33:/opt/something
vmount: Operation not permitted.

As reported by Doomlands of the Lunatics, apparently, AIX uses high ports to establish the connectivity to NFS Server, but Linux NFS Server requires low ports (below 1024). For this reason We have to tell AIX to use those reserved ports.

# nfso -o nfs_use_reserved_ports=1
Setting nfs_use_reserved_ports to 1

OK, now We can mount the directory on the Linux NFS server:

# mount 192.168.33.33:/opt/something /home/guest/tmp
